A $1-$mm$-$diameter nickel wire with electrical resistance of $0\mathrm{.}143\frac{}{m}$ is submerged horizontally in water at atmospheric pressure.

Given: The properties of water at the saturation temperature of $100C$ are

$=0\mathrm{.}0589\frac{N}{m^3}$

${}_l=957\mathrm{.}9k\frac{g}{m^3}$

$h_{fg}=2257{10}^3\frac{J}{k}g$

${}_V=0\mathrm{.}5978k\frac{g}{m^3}$

$=2217$

The parameter $L^{**}$ and the constant $C_{Cr}$ can be determined with the help of the following table:
